The resource picker lists a few hundred one-click services (Sonarr, Plausible, n8n, Uptime Kuma and so on) plus the generic sources: public Git repository, private repository, GitHub app, Dockerfile, Docker Compose, Docker image. We chose Public Git Repository and pointed it at Coolify's own examples repo, https://github.com/coollabsio/coolify-examples, with the base directory /javascript/runtimes/nodejs (a tiny Fastify server on port 3000). Coolify inspects the repo, proposes Railpack as the build pack and shows the branch, port and base directory for review.
